Thank you, operator. Good morning, everyone and thank you for joining our conference call to discuss BioXcel Therapeutics’ financial results and business highlights for the fourth quarter and full year of 2020. We appreciate everyone’s time and attention. Joining me on the call today are Richard Steinhart, Chief Financial Officer; Will Kane, Chief Commercial Officer; Frank Yocca, Chief Scientific Officer; Vince O’Neill, Chief Medical Officer; and Reina Benabou, Chief Development Officer. And we would like to extend a warm welcome to June Bray and Javier Rodriguez to our board and management team, strengthening our leadership team and bringing strategic experience to support the transformation of BioXcel. This is the historic time for BioXcel as we are preparing to transition to a commercial neuroscience-focused company. Today, we are pleased to announce that we have completed the submission of our new drug application to the FDA for the acute treatment of schizophrenia and bipolar disorder-related agitation. I am proud of our team’s hard work in completing these important milestones on schedule. We were able to accomplish this significant achievement with impressive speed from first-in-human trials to NDA submission in just over 2 years, supported by our powerful AI-based discovery and development platform. This is our first NDA and we believe if approved can be the first AI-derived drug to have received FDA approval. As our NDA application undergoes FDA’s review, we have taken steps to begin the transition to a potentially commercial stage organization and we are actively advancing our launch readiness initiative. In addition to establishing our commercial and medical teams with seasoned professionals, we are building our commercial infrastructure, including the design and structure of our sales force. Our medical science liaison team has been hired and is completing its training. This team will begin scientific exchange interactions by the end of this month. I am confident that we will be well prepared for the potential commercialization of 501, which if approved would be a unique and an innovative treatment in the U.S. to specifically address schizophrenia and bipolar disorder-related agitation. I am also pleased to report that two abstracts on SERENITY 1 and SERENITY 2 have been accepted for presentation at this year’s American Psychiatric Association Annual Meeting in early May. The potential approval of 501 will help pave the way for our broad neuroscience franchise expansion, establishing this candidate as an important new treatment across the agitation spectrum in multiple neuropsychiatric disorders. Due to 501’s unique mechanism of action, we are currently investigating three follow-on indications: dementia-related agitation, opioid withdrawal symptoms and delirium-related agitation as recently highlighted in our 501-focused KOL day. Over the past 12 months, we have made tremendous progress with the development of the additional programs with the goal of providing 501, if approved, to the millions of neuropsychiatric patients suffering from agitation and other stress-related symptoms. We plan to submit supplemental NDAs for these follow-on indications in the years to come. We recently announced positive data from the TRANQUILITY study, our Phase 1b/2 trial for the acute treatment of dementia-related agitation. To recap results from this trial, BXCL501 was well-tolerated with no severe or serious adverse events, such as syncope or fall. Statistically significant and clinically meaningful reductions in agitation were achieved with both 30 and 60 microgram cohorts at 2 hours post dose, as measured by the PEC, PS and modified CMI scales. Rapid and durable reductions in agitation were seen with the 60 microgram cohort across all efficacy endpoints with significant reductions in agitation lasting up to 8 hours. To build on the TRANQUILITY results, we have initiated a 46-patient multi-center, placebo-controlled TRANQUILITY expansion study, investigating a 40-microgram dose cohort of BXCL501 with 1-to-1 randomization. We believe this supplemental cohort will help to inform our comprehensive clinical development strategy targeting the full range of dementia care setting from long-term care centers to at-home care. Furthermore, our end of Phase 2 meeting with the FDA has been scheduled for the second quarter of this year, with plans to initiate our pivotal Phase 3 program in the second half of 2021. Turning to the RELEASE study, our Phase 1b/2 trial of BXCL501 for the treatment of opioid withdrawal symptom, we remain on track to report top line results later this month to further explore BXCL501’s potential to alleviate the debilitating side effects of withdrawal, thereby helping patients overcome their addiction. Last month, we initiated the PLACIDITY trial, a Phase 2 trial of BXCL501 for the treatment of ICU patients with delirium-related agitation. We expect to report top line results from this trial in the first quarter of 2022. Most delirium patients experience agitation, which we estimate occurs in approximately 4 million U.S. patients annually, often complicating overall patient care and extending hospital stays. Delirium occurs in numerous hospital treatment settings, including the ICU, surgical wards, hospital wards and emergency departments. Our strategy is to evaluate 501 in delirium patients across all these hospital settings, thus making this indication highly synergistic with the medical and commercial hospital-based infrastructure we are currently building in support of our first NDA. Lastly, BioXcel and its collaborators, the VA Connecticut Healthcare System and the Yale University Medical School, are investigating 501 for the first time as a potential chronic treatment in an at-home setting for patients suffering from PTSD related to alcohol and substance abuse disorders under a grant from the U.S. Department of Defense. As you can see, we are actively exploring BXCL501 potential across numerous neuropsychiatric and neurodegenerative disorders, advancing five distinct indications with the goal of creating a highly valuable neuroscience ventures. Our clinical trials in various disorders have shown that 501 is well-tolerated and has demonstrated a robust treatment effect at multiple dose ranges, helping to support a broad market strategy for the underlying diagnosis. We are passionate about potentially bringing this novel treatment to the millions of patients that lack effective and tolerable options and we continue to explore additional patient populations that are hallmarked by stress-related symptoms. We believe that BXCL501, if approved, has the potential to become the standard of care for the treatment of agitation. These significant developments reinforce the power of our AI platform in identifying and developing potentially best-in-class therapy. We continue to leverage this evolving drug innovation model to identify and develop new programs to expand our neuroscience pipeline in addition to 501. Now, I would like to turn the conversation to our immunooncology clinical candidate, BXCL701, our oral immunomodulator designed to stimulate both the innate and acquired immune systems. Back in November, we presented safety and efficacy data from the ongoing combination trial of 701 in KEYTRUDA at the Society of Immunotherapy for Cancer Annual Meeting. Additionally, we provided an update on the ongoing Phase 1b/2 trial in aggressive forms of prostate cancer at ASCO GU last month. Based on these encouraging anti-tumor activities seen in both cold and hot tumors, we believe 701’s mechanism of action, when combined with a checkpoint inhibitor, has the potential to enhance innate immunity and maybe effective at targeting difficult-to-treat tumors. We look forward to continuing to advance 701 with plans to provide top line results from both the Phase 1b/2 trial in aggressive forms of prostate cancer and the MD Anderson-led basket trial in advanced solid tumors in mid-2021. With that, I would like to turn the call over to our CFO, Richard Steinhart. Richard?
